Barnard, 1972a: 253 — Barnard & Barnard, 1983: 629 , fig. 10. — Lowry & Stoddart, 2003: 185 (catalogue). Type species. Megamoera suensis Haswell, 1879b , here selected (replacing Gammarus suluensis Dana, 1852 ). Included species. Parelasmopus includes 10 species: P. albidus ( Dana, 1852 ) ; P. echo J.L. Barnard, 1972a ; P. dancaui Ortiz & Lalana, 1997 ; P. mallacootaformis Ledoyer, 1984 ; P. setiger Chevreux, 1901 ; P. sowpigensis Lowry & Springthorpe, 2005 ; P. suensis ( Haswell, 1879b ) ; P. suluensis ( Dana, 1852 ) ; P. ya J.L. Barnard, 1972a ; P. zelei Ledoyer, 1983 . Remarks. Stebbing (1888) based the genus Parelasmopus on Gammarus suluensis Dana, 1852 . According to J.L. Barnard (1972a) , Stebbing (1888) misidentified his material. Stebbing based his concept of Parelasmopus on a species with a pair of dorsal spines on pereonite 7, but pereonite 7 is smooth in P. suluensis . At that time Barnard could not identify the species, but comparing Stebbing’s (1888) illustrations with Berents’ (1983) illustrations of the lectotype of P. suensis , it is clear that Stebbing had P. suensis . In reality Stebbing based his description of Parelasmopus on P. suensis , using material from Challenger station 186, near Thursday Island, Torres Strait ( 10º30’S 142º18’E ). According to ICZN (4 th edition, 1999) Article 70.3.1, this species may be selected as the type species, replacing Parelasmopus suluensis ( Dana, 1852 ) , originally chosen by Stebbing (1888) .
